Properties of Operations

Properties of Operations Commutative Property of Addition a + b = b + a Commutative Property of Multiplication a • b = b • a Associative Property of Addition (a + b) + c = a + (b + c) Associative Property of Multiplication (a • b) • c = a • (b • c)

Properties of Operations Distributive Property a(b + c) = ab + ac and ab + ac = a(b + c) Addition Property of Zero (Additive Identity Element) a + 0 = a and 0 + a = a Additive Inverse a + (-a) = 0 and (-a) + a = 0

Properties of Operations Multiplication Property of One (Multiplicative Identity Element) a • 1 = a and 1 • a = a Multiplicative Inverse a • 1/a = 1 Multiplication Property of Zero a • 0 = 0 and 0 • a = 0
